What two numbers multiply to 990 and add up to 119?

Here we answer the question: "What two numbers multiply to 990 and add up to 119?"

The answer to your question is:

9 and 110

Below we illustrate and prove that 9 and 110 multiply to 990 and add up to 119:

9 × 110 = 990
9 + 110 = 119

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 119x + 990 = 0

If so, the solution to factor the quadratic equation above is:

(x + 9 ) (x + 110)

To summarize, since 9 and 110 multiply to 990 and add up 119, you know that the following is true:

x² + 119x + 990 = (x + 9 ) (x + 110)
